METHOD OF AND IEAGHINE FOR HANDLING PLAST'EBFBQABD- To all whomc't mayconcern: I Be it known that we, OnVILLE L. RoU'r'r,

Gnovsn OfMoConnnpm-hhd HERBERT L.

Ghana, citizens of the United States,'resid ing in the city otLosrlr'l'igeles, county of Los Angeles, and State-of California, haveinvented certain new and useful Improve- "merits in Methods of andMachines for Han- 4 said fresh board in this condition without damagethereto. for-it must be handled in fiat-form and must be kept separateduntil it dries. I

The principal object of the present invention is to provide carriers forreceiving the fresh plaster board from the machine in which it ismanufactured, in flat form,jwith a minimum of handling, and we havediscovered that we can best handle it on carriers moving by gravity, onan incline, and that the plasterboard itself, as it is fed onto saidcarriers can be used for retarding or controlling the movement of thecarriers.

We have illustrated one practical embodiment of our invent'on in theaccompanying sheet of drawings, in which- Figure 1 is a side elevationof a machine embodying our invention; I

'Fig. 2 is a top plan view thereof; and Figs. 3, 4, 5 .and' 6 arevertical sectional Views taken on the and'6-6, respectively.

Referring now more in detail to the drawings, 1, 1, designate thesupporting frame members for the manufacture of the plaster board,designated B; On this frame are two rollers, 2, 2, which support anddrive a broad belt, 3, supported wit additional rollers 4, 4, on saidframe,'-as sceii; Two rblls of paper, P, P, are fed between two rollers,5, 5, and the plastic material, 6, is

fed thereto from a feed trough 7, as indicated. This mechanism forms nopart of the present invention, but serves to illustrate the discharge ofthe fresh finished board from the lower end of the frame 1.

Application filed April 17, 1919. Serial No. 291,971.

' iromany suitable position above the upper end of the frame 1, to apoint beyond the lower end of said frame 1, as shown. Carriers 9, 9, areprovided to run on said runway, said carriers comprising frame memberswith wheels, 10, 10, said frame members as here shown having a body ofopen or woven fabric, 11. downwardly-on said runway 8, one followingtheother andall moving together, the finished plaster board isdischarged onto said carriers as it is discharged from the belt 3. Thefeed of the fresh plasterboard onto the carriers can be controlled bythe drive for the belt 3, indicated as a belt 12, over pulley 13. Thecontact withthe new board, flatwrsepn the carriers serves to hold thecarriers to a speed corresponding to the speed of the'plaster boardbeing discharged from the belt 3, thus holding said carriers so thatthey move with the discharged plas ter board. At any suitable point,aputting knife, indicated at 14, can be arranged, to out said plasterboard into lengths on the frame of the carriers as they pass said knife,

be moved forwardly: so

The carriers can then to any suitable place and stored until the plasterboard is dry.

We are aware that many difierent forms of machines can be made embodyinthe idea ofi carriers to receive fresh p aster board, and moving down anincline, with the plaster board'operating to hold said carriers on theirdownward movement, and we do not, therefore, limit our invention to theform here shown for illustrative purposes, except as we may be limitedby the'hereto app pnded claims.

.' e claim:

' 1. Means for handling plasterboard which consists of an inclinedrunway, carriers to receive said plasterboard adapted to move along saidrunway under the place of discharge of said plasterboard, saidplasterboard holding said carriers to "a movement corresponding to thefeed speed of said plasterboard.

2. In combination with means for making and discharging plasterboard,carriers moving by gravity under said discharged plasterboard, saidcarriers being controlled in their movement by said plasterboard.

3. In c'ombination with means for making and discharging plasterboard,means for As saidcarriers move I corresponding to the feed movement ofsaid handling said plasterboard, comprising a runway under the place ofdischarge of said plasterboard, carriers adapted tomove along saidrunway and to receive said' plasterboard as it is discharged, and meanswhereby said plasterboard holdssaid carriers to a movement correspondingto the feed movement of the plasterboard.

4. In combination with means for feeding wet plasterboard in acontinuous strip, an inclined runway, carriers moving on said runwayunder the discharged plasterboard to receive the same in flat condition,said carriers being adapted to be held in their movement by saidplasterboard to a speed plasterboard.

5. The herein described method of handling wet'plasterboard, whichconsists in discharging the wet plasterboard onto car- I riers movmg bygravity and adapted to be held to a movement corresponding to the incontinuous ceive the same in fiat condition, the drag of saidplasterboard being used to retard the movement of said carriers alongsaid. in-

cline, substantially as shown and described. Signed at Los Angeles, LosAngeles county, Californ ia, this 28th day of Febru-" ary, 1919.
